ROLLER OR BALL BEARING.

Application filed January 22, 192-1. Serial No. 439,162.

To all who met may concern-r Be it known that l, lQinLVVnninLMPn'rnnsoN, asubjcct of the King of Sweden, residing at thitten-burg, inth county of Goteberg and Fiohus and Kingdom of Sweden, have inventednew and, useful Improvements in Roller or Ball Bearings, oi which thefollowing is a specification.

This invention relates to antitriction roller or ball "bearings, moreespecially to such roller or ball bearings, which are provided withsolid cages, and has for its object to provide a roller or ball cagewith recesses for the rollers or balls of such a shape that thepartition members of the cage between the rollers or balls become moreor less resilient.

According to this invention the said result is obtained by providingrecesses of such a form, that on the one contact surface of the saidpartition members of the cage, one or more points touch thecorresponding roller or ball, and on the other contact surface of thesame partition member one or more points displaced in relation to thosepreviously mentioned touch the adjacent roller or ball so that theconnecting line between two such contact points, located on oppositecontact surfaces, will not coincide or be parallel with the lineindicating the direction of movement off the rolling bodies. ilhisrelative displacement oi the respective contact points makes it possiblefor the partition members of the cage to yield when a pressure isapplied upon them from the rollers or balls when operative.

The invention will now be described with reference to the accompanyingdrawings which illustrate diagrammatically various forms of rollerbearings constructed in accordance with the invention wherein;

Figure 1 is an elevation of the improved bearing, a portion of the cagebeing broken away and shown in section.

Figure 2 is a section on the line 22 of Figure 1.

Figure 3 is an enlarged trag gmentary section taken in a planecorresponding to the plane in which the :sectional portion of Figure 1is taken.

Figure 4 is an elevation of a modified form of the bearing, a portion ofone part of the cage being broken away.

Figure .5 is an enlarged sectional view on nodiiiedform of theinvention.

Figure 7 is an enlarged sectional View on the line 77 of Figure 6, therollers being shown in elevation.

1 denotes the cage, 2 the rollers, 3 the recesses in the cage for therollers, 4: the partition members of the cage, 5 and 6 denote points ofcontact between the rollers 52 and the partition members 4: on the oneside of the partition member, and 7 is a single contact point on theother side of a partition mem ber l, which point is displaced inrelation to and disposed centrally therebetween the points 5 and 6.

From the figin'es it will be clear that when for some reason during theoperation of the bearing, one or more off the rollers 2 behind, apressure will result upon the points 5 and (3 of the partition members4: of the cage. If the recesses 3 in the roller cages are formed in sucha way, that the pressure "from a roller 2 on the left hand side of apartition member 4; is directed through the points 5 and 6 and thepressure from a roller 2 on the right hand side of the same member 4 isdirected through the point 7, the result will be a tendency to fie): thepartition member with the consequent yielding of the latter.

In Figure l the displacements of the contact points 5, 6 and 7 areprovided for in planes extending radially of the axis of the bearing,while in Figure 2 said displacements are ar *anged in an axialdirection. Referring more particularly to the form of the inventionillustrated in Figure 2, the cage is indicated at 1, the bearing rollersat 2 and the two points of contact between one side of each partitionand an adjacent roller 2 at 6. The opposite side of said partition whichengages an adjacent roller is in contact therewith at only one pointdesignated 7*. There is no reason why the devices shown in Figure 1 andFigure 2 should not be combined to obtain a still better effect.

In Figure 3 the recesses 3 in the cage 1 are wider than the rollers 2thus eliminating friction upon the flat side surfaces of the rollers. Inthis case the rollers when tending to move out of their regular positionwill easily be brought back by the pressure from the contact points 6'and -7 This last mentioned feature can be combined with the device shownin Figure 1.

This invention relates not only to roller bearings but to ball bearingsor the like.

What I claim is 1. A cage for anti-friction roller members havingrecesses for the rolling'members and partition members for spacing theroller members each partition member being so shaped that the rollingmember on one side has contact therewith at a plurality of points,whereas the rolling member at the opposite side has contact at a pointintermediate the points of contact on the first mentioned side wherebythe portion of the partition member lying between the points of contactis flexed upon application of pressure to the rollingmembers.

2. A cage for anti-friction rolling unembers having recesses for therolling members and partition members tor spacing the rollingme-nrbers,each partition member be-,

ing so shaped that the rolling members on both sides have contacttherewith at one or more points whereby each line connecting any contactpoint in one contact surface with any one of the contact points locatedon the opposite contact surface of the same partition member will beobliquely disposed with relation to the line indicating the direction ofmovement of the rolling member so that the partition member will beflexed upon application of pressure tothe rolling member.

In testimony whereof I have affixed my signature.
